Quick answer

What is lockout tagout training?

Lockout tagout, or LOTO, is the safe isolation of plant and machinery so it cannot be started or release stored energy while someone is working on it. This course teaches how to plan, install and prove an isolation, and how to return equipment to service safely. KeyOstas delivers it as a half-day in-company course.

Covers the safe isolation of plant and machinery
Lock off, tag out, prove the isolation, return to service
Built around a reliable, repeatable isolation system
Certificate of attendance for every delegate
Many serious injuries happen when machinery starts up, or releases stored energy, while someone is working on it. Lockout tagout prevents that: the equipment is isolated, physically locked off, and tagged so nobody can re-energise it until the work is done. This course gives the people who isolate plant and machinery a sound, repeatable method: assessing and selecting the isolation, planning and installing it, draining, venting and proving it is safe, and then returning the equipment to service in a controlled way.

Is it right for you

Is this course right for your team?

It is for the people who isolate plant and machinery to work on it.

Right for you if…

Your staff work on plant or machinery that must be isolated first
You have maintenance, engineering or production staff who lock off equipment
You want a reliable, consistent isolation system across the site
You need staff who prove an isolation rather than assume it
You want safe reinstatement built into the method

A different course fits better if…

Your team never isolates plant or machinery
You need electrical safe-isolation training to a specialist standard only
You want a regulated, accredited qualification: this is a certificate of attendance

FAQ

Lockout tagout training: frequently asked questions

What is lockout tagout?
Lockout tagout, or LOTO, is the safe isolation of plant and machinery: the equipment is isolated, physically locked off and tagged so it cannot be started, or release stored energy, while someone is working on it.
How long is the course?
Half a day, delivered in-company at your premises, for up to 16 delegates per course.
Who should attend?
Maintenance, engineering and production staff, and anyone who isolates plant or machinery in order to work on it.
Is lockout tagout a legal requirement?
Employers must make sure work equipment is safe to work on. The Provision and Use of Work Equipment Regulations 1998 require effective isolation, and HSE guidance HSG253 sets out safe isolation. LOTO is how that is achieved in practice.
Why do you need to prove an isolation?
Because an isolation can fail or be incomplete. The course teaches delegates to test and prove the equipment is dead rather than assume it, before any work starts.
Does the course cover returning equipment to service?
Yes. Safe reinstatement and return to service is part of the method, so equipment is brought back into use in a controlled way.
Can the course use our own equipment?
Yes. Delivered in-company, it can be built around your own plant, machinery and isolation procedures.
Is this an accredited qualification?
It is a KeyOstas course with a certificate of attendance: practical training rather than a regulated qualification.
